An analysis of previously uncharted chemical contents, mostly carbohydrates, in U.S.-consumed mushrooms shows that these fruity edible bodies of fungi could be tailored into dietary plans to help fill various nutritional needs.
Using modern analytic tools, scientists at the University of Illinois at Urbana-Champaign found that the six mushroom varieties tested - in raw and cooked forms and at various harvest times and maturity levels - are rich in total dietary fibers, including those associated with cholesterol-lowering (chitin) and healthy hearts (beta-glutan). The findings appear online in advance of regular publication by the Journal of Agricultural and Food Chemistry. The same researchers last year reported in the same journal the carbohydrate profile of selected plum and prune products. The findings will become part of the U.S. Department of Agriculture’s National Nutrient Database. "What we’ve reported in these papers are the complete carbohydrate profiles of these two lines of popular foods," said George C. Fahey Jr., a professor of nutritional sciences in the department of animal sciences at Illinois. "These profiles include the digestible carbohydrates, the starches and the fermentable fibers that reach the large bowel. This work was important to the two commodity organizations that funded this research, because they had little information on these components."
It was already known that mushrooms offer high-quality protein, vitamins, unsaturated fatty acids and fiber, but a precise carbohydrate breakdown had been elusive. The mushrooms studied were white button, crimini and portabella, all of which represent different maturity levels of Agaricus bisporus, and maitake (Grifola frondosa), shiitake (Lentinus edodes) and enoki (Flammulina velutipes). The latter two mushrooms were analyzed only in their consumed cooked form. "The maitakes and shiitakes tended to be very similar in their nutrient concentrations, and quite a bit different than the others," said Cheryl L. Dikeman, a doctoral student in Fahey’s lab and lead author on both papers. "Portabellas were off on their own in terms of their contents of oligosaccharides, beta-glucans and chitin."

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.
The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...
Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.
The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...
In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.
In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
